Powder metallurgy temporary storage machine gear producing and machining method

The invention discloses a powder metallurgy temporary storage machine gear producing and machining method. The method comprises the following steps that S1, iron powder and a chemical adjusting agent are mixed and scientifically adjusted; s2, pouring the iron powder prepared in the step S1 and the adjusting agent into an extrusion mold, and shaping to form a gear; s3, the gear formed in the step S2 is taken out, and then a threaded hole is punched in the corresponding position; and S4, after the step S3 is completed, the gear is quenched after the threaded hole is punched, and all processes of the gear can be completed. The production and machining method of the powder metallurgy temporary storage machine gear is more perfect, the machined temporary storage machine gear is rust-proof, wear-resistant, long in service life, high in production efficiency and suitable for large-scale application and popularization, downward pressure of a pressing die 9 of the gear is controlled through a pressure sensor 82 in an
